SOLDERlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 223,849, dated January27, 1880.

. Application filed December 10, 1879.

To all whom it may of Baltimore city,

State of Maryland, have invented certain new and useful Improve clarethe same to aotly described as had to the accompanying d I herebydeolearly, and exreference being drawings, in whichbe fully, follows,

Figure 1 is a side elevation of the device 10 Fig. 2, a similar view,enlarged, of the tip of the revolving rod; of the latter.

and Fig. 3 is an end view My invention relates to that class ofsoldering-irons in use for capping provision-cans and it consists incertain improvements upon the invention described in 219,815, granted toLetters Patent N 0.

me September 23, 1879.

In that class of capping-irons in which the handle levolves ab out thecenter-rod an obstacle was met in the wearing of the centerrod from therevolution of the handle, causcan.

In my patent above referred to is described an iron whose rod revolveswith the handle,

instead of the handle about the rod, whereby the wearing of the rod isprevented entirely.

The center-rod in the patented iron is provided with a swiveling tiphaving a pyramidal point, which is stepped in the center 'hole of thecap and permits the air to escape. An

obstacle was,

case its pyramidal away from the ed and the slightest however, workingof the iron, which it is mv present invention to obviate. liable to rustand refuse to met in the practical the object of The tip was swivel, inwhich point would ream the .tin ges of the hole in the cap, rusting ofthe exposed iron would prevent the adhesion of the drop of solder usedin sealingthe can.

I now tirely, to admit of its turn friction or reaming do away with theswiveling tip enand so construct the end of the rod as ing smoothly andwithout in the cap-hole, and at the same time admit of the escape of theair.

In the drawings,

.steel and cylindrical i has a flattened side, a, As an alternative, thelygonal in cross-section inder is more chea readily fitted.

A is a rod, preferably of n shape, except that it extending from a to a.rod may be made pobut the flattened cyl ply constructed and more Arms 0c extend from the sleeve E and sus- 6 tain the tool-holder F, whoseshank is slotted at g g, and through the slots pass screws O 0, wherebythe holder may be adjusted parallel to the axis of revolution and atvarious distances therefrom. 7

The tip 0 of the rod A is designed to revolve smoothly in the cap-hole,and has the form of a cone flattened or grooved on one or more sides.The object of this construction is as follows As the angle between thefaces 0 c of the tip is less than that between the conical surfaces v173, the latter constitute the bearingsurfaces for the revolution of therod, and apertures are left opposite the faces 0 0 for the escape of theair.

As the faces t z are curved and smooth they do not abrade or ream awaythe tin, and the use of the iron keeps them true and smooth.

In operation, the iron G is heated, and the cap being laid in applied tothe groove, the rod A is slipped in the center hole and the iron isrevolved by means of the handle D upon the solder until it is evenlyspread and melted in the groove.

What I claim is- 9 1. In combination with the terminal swivelin ghandleB, the tool-holder handle D, mounted upon and arranged to rotatewith the smoothpointed rod A, as set forth.

2. The combination, in rod having. a rounded tip adapted to rotatefreely in the center hole of the can-cap, a toolholder handle slidingfreely on the rod, but rotating therewith, and a terminal swivelinghandle, B, as set forth.
